[Arthur Heymans (Code Review)]

Hello Kyösti Mälkki, Aaron Durbin, Julius Werner, build bot (Jenkins), Patrick Georgi, Martin Roth,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/36273

to look at the new patch set (#13).

Change subject: lib/cbmem_top: Add a common cbmem_top implementation

lib/cbmem_top: Add a common cbmem_top implementation

This adds a common cbmem_top implementation to all coreboot target.

In romstage a static variable will be used to cache the result of
cbmem_top_romstage.

In ramstage if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is set a global variable
needs to be populated by the stage entry with the value passed via the
calling arguments. if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is not set the
same implementation as will be used as in romstage.
